Worked example: swapping two fixtures at $110/hr
Two fixture installs at 1.5 labor-hours each is 3 hours — $330 at $110/hr — plus the trip fee baked into flat-rate pricing, so a base near $330. Easy access keeps the multiplier at 1.08, landing the estimate around $355 plus the fixtures themselves. Quotes from $285 to $480 are normal; anything over $600 for two swaps is flat-rate book pricing in an expensive metro.
- • Supply your own fixtures and you pay labor only — but many plumbers won't warranty customer-supplied parts.
- • A $350 quote for a $120 faucet swap usually means a 2-hour minimum plus trip fee, not dishonesty.
- • Slab leaks and crawlspace repipes are where access multipliers bite hardest — budget 1.5–2× the open-access price.
Flat-rate vs hourly: which protects you
Flat-rate (book) pricing means the quote doesn't grow if the job runs long — good for complex diagnostics. Hourly is cheaper for quick, well-defined jobs. Always ask which model the quote uses, and whether the trip fee is credited against the work. Permits ($50–$300) are required for water heaters and repipes in most jurisdictions and should appear as a line item.
